Time Capsule with N and G? Please Help!

A MBP (N capabilities) and a MB (G capabilities) both wirelessly backing up to 500GB Time Capsule. I also have a 500GB external hooked up to the Time Capsule which stores my movies and TV shows which stream to my Apple TV and XBox. I also Have an iPhone and a Wii (G capabilities).

I was wondering if it is possible to hook up my airport express (G) to the Time Machine and put everything wireless on that band and put my MBP on the N band? However, will I still be able to do wireless Time Machine backups from the MB and access the external hard drive?

yes, run an ethernet cable between the time machine and the express,
set the TM for N only,
Set up different network names MyNetwork-G & MyNetwork-N or whatever
on the express on the internet settings page, put connection sharing to "off bridged mode"

anything connected to the G network, will be just as if it was connected via ethernet to the Time machine (well not speed wise, but you know what i mean)

Yes. I finally found some documentation (not as concise as yours and a bit more confusing) on how to do it.

However, I set it up and did not notice any significant improvements and when I tested a backup from a G device it was taking for ever to "prepare for backup" But it took forever even when I just used the Capsule in compatibility mode so I'm not sure if there is any advantage to it.
